When loading any type of file through the "Others" field. If the path to the file has any spaces, it will not load the file. Neither escaping the spaces with \ ,nor wrapping the file path in quotes has any effect.

So far I've observed this behavior upon loading configs and patch files.
This is inconsistent with how twad loads mods, as spaces in file names don't impact functionality.
Perhaps this is related but when any filename provided through the "Others" field. It has to be the full path name (without spaces present). Again inconsistent with the $DOOMWADDIR being the CWD that we see when loading in our mods.

I'm running v0.20.0 binary
